If you're healthy, you should be fine.

Vitamin D is crucial but I'm sure you're outside frequently & don't lather on sunscreen. A vit D supplement would be good if it was winter or spring though.

Zinc is probably helpful.

Start fasting if you start to feel ill (I naturally tend to do this anyway). Otherwise eat your ruminant meat for nutrition.

The only time I've gotten sick in the last 4 years has been after a series of late nights with alcohol. I was run down & I'm pretty sure that it was Rona I caught.
